DOOR-HINGE.

Specification of Letters Patent.

Application filed January 4, 1916. Serial No. 70,165.

To all whom it may concern:

Be it known that I, MELVILLE B. GUN- NINGHAM, a citizen of the United States, and a resident of Fort Worth, in the county of Tarrant and State of Texas, have made an Improvement in Door-Hinges, of which the following is a specification.

My invention pertains to that type of door hinges in which the leaveslie in parallel planes "and overlap and are pivoted together.

The details of construct-ion, arrangement, and operation are as hereinafter described, and illustrated in the accompanying drawing, in which:

Figure 1 is a face or side view of a portion of a jamb and swinging door connected by my improved'hinge'. Fig. 2 isa vertical section on line 2-2 of Fig. 3. Fig. 3 is a horizontal sect-ion on line 3-3 of Fig. 1..

Fig. 4 is a vertical section on line 44 of Fig. 1. Fig. 5 is a perspective View of the hinge proper. Fig. 6 is a horizontal section on line 6-6 of Fig. 1. i

a and 6 indicate, respectively, a jamb and swinging door, the same having a knuckle or table-leaf joint, as shown bestin Fig. 6. Horizontal kerfs or slots 1 and 2 are formed adjacent-1y in the meeting edges of the jamb and door. The hinge proper is formed of metal plates (see Fig. 5) having broad fiat bodies or shanks 3 and 3 which are provided with pendent side flanges 4 and 4 and circular terminal ears 5 and 5 formed on the inner or meeting ends. of the shanks,

and which overlap and are pivotally connected by a rivet 6. The hinge thus constructed is applied by inserting its flat shanks 33 in the opposite kerfs 1- and 2 of the jamb and door, as shown in Figs. 1, 2, 3, so that the pivot is coincident with the axis of the joint between the parts a and b. Screws 7 are inserted through holes in the pendent side flanges 4 and 4, as shown in Figs. 1 and '2, to secure the hinge in place, and thereby connect the door'to the amb so that it is supported firmly, but

may be easily detached if required.

: It will be understood that the weight of the door is supported by its leaf 6 resting on the ear 5 of the leaf 3 and the latter in turn resting on the underside of the kerf 1 in the jamb a.

It will be seen that by 'the construction and arrangement described thereis no crack or vertical opening in the joint between the MELYILLE BOYD CUNNINGHAM.
